Rui Fan commented on FLINK-35040:
---------------------------------
I attached 3 flamegraphs here, these flamegraphs are generated on flink
benchmark server, many thanks to [~Zakelly] for the help.
>From these flamegraphs, we cannot find any org.apache.commons.io code is
>called (I search commons in flamegraph). But the performance regresses after
>commons.io is upgraded. It's a little strange.

> The performance of serializerHeavyString regresses since April 3, and had not
> yet recovered on April 8th.
> It seems Java 11 regresses, and Java 8 and Java 17 are fine.
